Learn more. Aqueous flow batteries are considered very suitable for large-scale energy storage due to their high safety, long cycle life, and independent design of power and capacity. Especially, zinc-iron flow batteries have significant advantages such as low price, non-toxicity, and stability compared with other aqueous flow batteries.
The flow battery possesses a stack for redox reaction and two external reservoirs for storing electrolyte. Benefiting from its distinctive architecture, flow battery offers the advantage of decoupling and adjusting both power and capacity independently, thereby realizing an excellent design flexibility .
Thus, the cost-effective aqueous iron-based flow batteries hold the greatest potential for large-scale energy storage application.
Flow batteries provide promising solutions for stationary energy storage but most of the systems are based on expensive metal ions or synthetic organics. Here, the authors show a chlorine flow battery capitalizing the electrolysis of saltwater where the redox reaction is stabilized by the saltwater-immiscible organic flow.
Nevertheless, the all-iron hybrid flow battery suffered from hydrogen evolution in anode, and the energy is somehow limited by the areal capacity of anode, which brings difficulty for long-duration energy storage.
